ABSTRACT
Background: Postoperative nausea and vomiting (PONV) prophylaxis with dexamethasone may produce significant hyperglycemia in the postoperative period. Aim: To evaluate if this effect is of greater severity in type 2 diabetics compared with non-diabetic patients. Material and Methods: Forty non-diabetic and thirty type 2 diabetic patients undergoing laparoscopic cholecystectomy were studied in a prospective and double-blind fashion manner. Patients were randomly distributed into 4 groups: Group I, non-diabetics control (n = 20), Group II, non-diabetics dexamethasone (n = 20), Group III, type 2 diabetics control (n = 15), and Group I V, type 2 diabetics dexamethasone (n = 15). Immediately after induction, patients in groups I and III received isotonic saline and patients in the dexamethasone groups received 8 mg iv of the steroid. Capillary blood glucose concentrations were measured at baseline and every 2 hours during the first 12 hours since the start of surgery. A linear mixed effect model, adjusted for baseline capillary glucose concentration, age and duration of surgery was used to analyze the data. Results: No effect of the presence of diabetes mellitus was observed in the evolution of glucose concentrations. There was a difference in capillary glucose concentrations between patients who received dexamethasone and placebo that started 2 hours post-intervention, reaching a mean maximum difference of 34 mg/dl (adjusted model, p < 0.001) at 10 hours post-intervention. Conclusions: In this study, Type 2 diabetic patients did not show a higher susceptibility than non-diabetics to develop postoperative hyperglycemia after the use of prophylactic dexamethasone for PONV.

En los últimos años el despertar transoperatorio es uno de los principales temores de los enfermos que van a ser intervenidos quirúrgicamente y se relaciona a consecuencias como el síndrome de estrés postraumático y a las implicaciones legales resultantes. Diversos reportes que han enfatizado la elevada incidencia del despertar transoperatorio y sus efectos adversos se han diseñado diferentes técnicas para su detección temprana y monitorización; entre los cuales el más importante es el índice biespectral (BIS). El objetivo principal del presente trabajo es el de comparar el consumo de agentes anestésicos durante la anestesia general, monitorizando parámetros hemodinámicos vs. valores BIS. Se realizó un estudio prospectivo, longitudinal observacional y comparativo en la unidad de quirófano y salas de recuperación del Instituto Gastroenterologico Boliviano-Japonés desde junio-agosto 2008 ingresan a este estudio 40 pacientes, de ambos sexos, ASA l-ll, edad entre 20-60 años, programados para cirugía abdominal. Se aplico una ficha de recolección de datos aleatoriamente divididos en 2 grupos de estudio: Grupo I se dosifico los agentes anestésicos a la monitorización del grado de hipnosis mediante el BIS. Grupo II se dosifico los agentes anestésicos a la monitorización de signos clínicos y cambios hemodinámicos. Según los resultados obtenidos se puede observar menor dosificación de drogas durante la anestesia general, en el Grupo monitorizado con BIS con relación al Grupo que se monitorizó con cambios hemodinámicos, lo que significa mayor dosis de anestésicos en los monitorizados con cambios hemodinámicos.
In recent years, intraoperative awakening is one of the main fears of patients who will undergo surgery and is related to consequences such as posttraumatic stress syndrome and the resulting legal implications. Several reports have emphasized the high incidence of intraoperative awakening and adverse effects are designed techniques for early detection and monitoring, among which the most important is the bispectral Índex (BIS).The main objective of this study is to compare the use of anesthetics during general anesthesia, hemodynamic monitoring vs. BIS valúes. We performed a prospective, longitudinal observational and comparative unit of operating and recovery rooms Gastroenterological Bolivian-Japanese Institute from June to August 2008 entered this study 40 patients of both sexes.ASA l-ll, aged between 20 - 60 years, scheduled for abdominal surgery. It applied a data collection sheet randomly divided into 2 study groups: Group I was dosed anesthetic agents to monitor the degree of hypnosis through the BIS. Group II was dosed anesthetic agents to the monitoring of dinical and hemodynamic changes. According to the results you can see lower dosage of drugs during general anesthesia in the BIS monitored group compared with the group that was monitored with hemodynamic changes, which means higher doses of anesthetics on the hemodynamic changes monitored.
